**Excerpt:** This tutorial will show you how to customize the Dynamic Choices option on Checkbox, Multiple Choice, and Dropdown fields. 

**Content:**

Would you like to customize the **Dynamic Choices** options for your **Checkbox**, **Multiple Choice**, and **Dropdown** fields? If you’re using **Dynamic Choices** but want to exclude specific posts, pages, or categories, then this is the tutorial for you!

The **Multiple Choices**, **Checkboxes**, and **Dropdown** fields can be configured to [dynamically display post or page titles as **Dynamic Choices**](https://wpforms.com/docs/how-to-set-dynamic-field-default-values-in-wpforms/ "How to Set Dynamic Field Default Values in WPForms").

By default when **Dynamic Choices** is enabled, all published items of that specific post type or taxonomy will display.

For example, when **Dynamic Choices** is set to **Post Type**, and the **Dynamic Post Type Source** is set to **Posts**, all published posts will be displayed as field choices.

![Using dynamic choices for the post type of posts will dynamically generate a list of all the published posts on your site.](https://wpforms.com/wp-content/uploads/2021/02/wpforms-using-dynamic-choices-1.jpg)For our tutorial, we’ll display a dropdown of dynamically generated post titles from our site.

## Creating the Form

To begin, we’re going to create a form that captures the name, email, the ability for the visitor to select which post they liked best, and then a comments section as well.

For this reason, we’ll add a **Name, Email, Dropdown, and Paragraph Text** form fields to our form.

Once you’ve added the **Dropdown** field, click the **Advanced Options** and in the **Dynamic Choices** dropdown click **Post Type**. This will bring up another dropdown for **Dynamic Post Type Source**. When you see this second dropdown, select **Posts** from the dropdown and click **Save** on the form.

![By default when Dynamic Choices is enabled using the Post Type of Posts, all published posts will be displayed.](https://wpforms.com/wp-content/uploads/2021/02/wpforms-add-dynamic-choices.jpg)If you need any help in creating your form, [please review this documentation](https://wpforms.com/docs/creating-first-form/ "Creating Your First Form").

## Adding the Snippet to Include Posts from a Single Category

You can even customize these options further by using code snippets. You can only include posts from a particular category or even exclude posts from a particular category.

For instance, in our tutorial, we want to only show posts from a specific category, so our code snippet will be added that will only populate our Dropdown with posts from category **11**.

For help in adding code snippets to your site, [please see this tutorial](https://wpforms.com/developers/how-to-add-custom-php-or-javascript-for-wpforms/ "How to Add Custom PHP or JavaScript for WPForms").

```

/**
 * Limit posts or pages displayed by category.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
 
function wpf_dynamic_choices_categories( $args, $field, $form_id ) {
     
    // For field #10 in form #851, only show entries in category #37
    if ( '851' == $form_id && '10' == $field[ 'id' ] ) {
 
        $args[ 'category' ] = '22';
 
    } 
     
    return $args;
     
}
 
add_filter( 'wpforms_dynamic_choice_post_type_args', 'wpf_dynamic_choices_categories', 10, 3 );
```

To find the ID number of your categories, [check out this tutorial](https://www.wpbeginner.com/beginners-guide/how-to-find-post-category-tag-comments-or-user-id-in-wordpress/ "How to Find Post, Category, Tag, Comments, or User ID in WordPress").

Remember to change your form and field ID in your code snippets to match your form and field ID number. If you need help finding your form and field ID numbers, please [review this tutorial](https://wpforms.com/developers/how-to-locate-form-id-and-field-id/ "How to Locate Form ID and Field ID").

### Limiting Multiple Forms for Multiple Category IDs

Did you know that you can also have this code snippet for various forms and fields?

The code below limits dynamic options within two different forms:

- Field ID `1` of form ID `363` to display only posts with the category ID `11`
- Field ID `20` of form ID `225` to display only posts from category ID `5`

```

/**
 * Limit posts or pages displayed by category.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
 
function wpf_dynamic_choices_categories( $args, $field, $form_id ) {
 
    // For field #1 in form #363, only show entries in category #11
    if ( '363' == $form_id && '1' == $field[ 'id' ] ) {
 
        $args[ 'category' ] = '11';
 
    // For field #20 in form #225, only show entries in category #5
    } elseif ( '225' == $form_id && '20' == $field['id'] ) {
 
        $args[ 'category' ] = '5';
 
    }
 
    return $args;
}
 
add_filter( 'wpforms_dynamic_choice_post_type_args', 'wpf_dynamic_choices_categories', 10, 3 );
```

### Limiting by Taxonomy

A [taxonomy](https://www.wpbeginner.com/glossary/taxonomy/ "What is: Taxonomy") is a term used in WordPress to define things like **Categories** and **Tags**.

If the **Dynamic Choices** is set to **Taxonomy**, and the **Dynamic Taxonomy Source** is set to **Categories**, all categories will be used for the field choices.

![It is also possible to exclude categories when showing all taxonomies as choices with the code snippet below](https://wpforms.com/wp-content/uploads/2021/02/wpforms-dynamic-choices-cats-or-tags.jpg)However, you can exclude specific categories using the snippet below.

```

/**
 * Exclude categories from dynamic choices.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
 
function wpf_dev_dynamic_choices_exclude( $args, $field, $form_id ) {
 
    if ( is_array( $form_id ) ) {
        $form_id = $form_id[ 'id' ];
    }
 
    // Only on form #212 and field #16
    if ( $form_id == 212 && $field[ 'id' ] == 16 ) {
 
        // Category IDs to exclude
        $args[ 'exclude' ] = '4,5,6,11';
    }
 
    return $args;
 
}
 
add_filter( 'wpforms_dynamic_choice_taxonomy_args', 'wpf_dev_dynamic_choices_exclude', 10, 3 );
```

This snippet will exclude categories with IDs 4,5,6, and 11 from the dynamic choice options. If you replace `exclude` with `include` in the snippet above, it’ll only show categories with the IDs you’ve added.

![Now only the posts, pages, tags or categories that you've set in your snippet will populate your dropdown.](https://wpforms.com/wp-content/uploads/2021/02/wpforms-limiting-dynamic-choices.jpg)### Displaying Only Future Posts

```

/*

function wpf_dev_only_future_posts( $args, $field, $form_id ) {
     
    // Only run this snippet on form ID 2575 & only on field ID 19
    if ( '2575' == $form_id && '19' == $field[ 'id' ] ) {
  
        // If the Dynamic Choices is set to Post Type
        // Look for and only display the posts that have been scheduled with a future date
        $args[ 'post_status' ] = [ 'publish', 'future' ];
  
    }
     
    return $args;

    // Only run this snippet on form ID 2519 & only on field ID 3
    if ( '2519' == $form_id && '3' == $field[ 'id' ] ) {
  
        // If the Dynamic Choices is set to Post Type
        // Look for and only display the posts that have been scheduled with a future date
        $args[ 'author' ] = get_current_user_id();
  
    }
     
    return $args;
  
}

    // Only run on form ID 526
    if ( '526' == $form_id ) {
 
        // The author ID is equal to 9
        $args[ 'author' ] = '9';
    }
 
    return $args;

function wpf_dev_dynamic_choices_include( $args, $field, $form_id ) {
 
    if ( is_array( $form_id ) ) {
        $form_id = $form_id[ 'id' ];
    }
 
    // Only on form #122 and field #11
    if ( $form_id == 122 && $field[ 'id' ] == 11 ) {
 
    // Category IDs to include - 87 is parent; 88 and 89 are child categories of this parent
        $args[ 'include' ] = '87,88,89';
    }
 
    return $args;
 
}
 
add_filter( 'wpforms_dynamic_choice_taxonomy_args', 'wpf_dev_dynamic_choices_include', 10, 3 );
```

## FAQs

#### Q: How can I customize this for a Woocommerce category?

**A:** For Woocommerce taxonomies, on the Advanced tab of your **Checkbox**, **Dropdown**, or **Multiple Choice** field, set the **Dynamic Choices** to **Product,** and for the **Dynamic Taxonomy Source**, select **Product categories**.

Then if you only wanted to include specific categories, you would find the ID in the same manner as you did above. From the WordPress admin, click **Categories** found under **Products** in the WordPress admin menu on the left. Click each **Product Category** you want the ID. The URL will look something like this:
`?taxonomy=product_cat&tag_ID=90&post_type=product&wp_http_referer=%2Fwp-admin%2Fedit-tags.php%3Ftaxonomy%3Dproduct_cat%26post_type%3Dproduct`

For this example, the ID number would be **90**

Therefore, your snippet would be as follows.

```

/**
 * Include certain Woocommerce categories from dynamic choices.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
   
function wpf_dev_dynamic_choices_exclude( $args, $field, $form_id ) {
   
    if ( is_array( $form_id ) ) {
        $form_id = $form_id[ 'id' ];
    }
   
    // Only on form #2620 and field #11
    if ( $form_id == 2620 && $field[ 'id' ] == 11 ) {
   
        // Product Category IDs to include
        $args[ 'include' ] = '90,95,98';
    }
   
    return $args;
   
}
   
add_filter( 'wpforms_dynamic_choice_taxonomy_args', 'wpf_dev_dynamic_choices_exclude', 10, 3 );
```

Remember to change your form and field ID in your code snippets to match your form and field ID number. If you need help finding your form and field ID numbers, please [review this tutorial](https://wpforms.com/developers/how-to-locate-form-id-and-field-id/ "How to Locate Form ID and Field ID").

#### Q: How can I show only certain products from a Woocommerce category?

**A:** Of course. You’d set up your **Dynamic Choices** to**Product** and for the **Dynamic Taxonomy Source**, select **Product categories**.

And instead of using the product category ID, you would use the name.

```

/**
 * Include products from a specific category from dynamic choices.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
  
function wpf_dev_dynamic_choices_exclude( $args, $field, $form_id ) {
  
    if ( is_array( $form_id ) ) {
        $form_id = $form_id[ 'id' ];
    }
  
    // Only on form #2620 and field #11
    if ( $form_id == 2620 && $field[ 'id' ] == 11 ) {
  
        // Category IDs to exclude
        $args[ 'product_cat' ] = 'Decor';
    }
  
    return $args;
  
}
  
add_filter( 'wpforms_dynamic_choice_post_type_args', 'wpf_dev_dynamic_choices_exclude', 10, 3 );
```

**Decor** is the name of our **Product Category**. Remember to change this to match your own needs.

#### Q: How can I show posts from a custom taxonomy in a WPForms dropdown field?

**A:** To display posts from a custom taxonomy in a WPForms dropdown field, you need to modify the dynamic choice arguments. Currently, the provided examples in our documentation cover categories. Here’s an example that shows how to customize the code to fetch posts from a specific taxonomy.

```

/**
 * Customize WPForms dynamic choices to show posts from a specific taxonomy.
 *
 * @link https://wpforms.com/developers/how-to-exclude-posts-pages-or-categories-from-dynamic-choices/
 */
 
function wpf_custom_dynamic_choices( $args, $field, $form_id ) {
 
    // For field #4 in form #25107012, only show entries in taxonomy term ID 8
    if ( '25107012' == $form_id && '4' == $field['id'] ) {
 
        $args[ 'tax_query' ] = array(
            array(
                'taxonomy' => 'samples', // Replace with your custom taxonomy
                'field'    => 'term_id',
                'terms'    => array( 8 ), // Replace with your term ID
            ),
        );
    }
 
    return $args;
 
}
add_filter( 'wpforms_dynamic_choice_post_type_args', 'wpf_custom_dynamic_choices', 10, 3 );
```

The `tax_query` array is used to specify the custom taxonomy (samples in this example) and the term ID (8 in this example). You should replace ‘samples’ and 8 with your own taxonomy and term ID as needed. For more information on tax queries, please check out the [WordPress documentation](https://developer.wordpress.org/reference/classes/wp_query/#taxonomy-parameters "WP Query taxonomy parameters").

And that’s it! You’ve now learned the various ways to customize dynamic choices in WPForms.
