In order to limit the product attributes in a custom template of WooCommerce, you can use the wp_get_post_terms() function.

Here’s an example of how you can use this function to limit the product attributes in a custom template:

$attributes = wp_get_post_terms( get_the_ID(), 'pa_color', array( 'fields' => 'all' ) );
foreach ( $attributes as $attribute ) {
    echo $attribute->name;

This code snippet will get all the terms for the attribute ‘pa_color’ of the current product, and then it will loop through them, displaying the name of each attribute.

You can change the attribute name ‘pa_color’ to the desired attribute name.

You can also use wp_get_post_terms to limit the number of terms by adding a ‘number’ parameter:

$attributes = wp_get_post_terms( get_the_ID(), 'pa_color', array( 'fields' => 'all', 'number' => 3 ) );

This will limit the number of attributes to 3.

Another method is to use get_the_terms() function, which is similar to wp_get_post_terms() but it returns an array of term objects.

$attributes = get_the_terms( get_the_ID(), 'pa_color' );
foreach ( $attributes as $attribute ) {
    echo $attribute->name;

In both cases, you can then limit the number of attributes displayed by using the array_slice() function to slice the array to the desired number of items.

$attributes = array_slice( $attributes, 0, 3 );

This will limit the $attributes array to the first 3 items.

Make sure that you have the correct attribute name and you are using the right function and parameters. Also, you need to make sure that the template you are editing is the right template and it is being used in the right place.
