Problem:

The issue here is that the user's custom archive pagination was exceeding the page width limit as they had 30 plus pages in their pagination.

Solution:
I suggest breaking up your pagination in to blocks rather than having it list out all the possible pages.

To do this you will need to select your pagination and add a value for the Pages to Skip field.

This option can be found when you've selected your pagination block and check the pagination settings sidebar.

Problem:

The issue here is that the user wanted to integrate the select2 dropdowns for their Toolset forms Generic fields.

Solution:

This can be done by importing the select2 javascript and css library.

Add the following to your custom code snippets at Toolset->Settings-> Custom Code and activate it.

wp_enqueue_script('select2_js', '//cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/js/select2.min.js', array(), null, true);
wp_enqueue_style( 'select2_css', '//cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css' );

From there you will need to add the following JS to your Form's JS section to enable the select2 for your field.

jQuery(document).ready(function() {
  jQuery('.class-goes-here').select2();
});

Now you will need to replace 'class-goes-here' with the ID/Class of the custom field that is generated on the frontend.

For further information on the usage of Select2 I recommend looking at the documentation below.
