Problem: I would like to know more about the consistency discrepancies between "select" type Views filters and CRED inputs.
Solution: CRED and Views select fields can use Bootstrap form input styles if you tell Toolset to include Bootstrap in Toolset > Settings > General > Bootstrap Loading. In CRED form shortcodes, you have the option of using Bootstrap styles or not by modifying the shortcode attributes. So select tags in Views shortcodes and CRED forms will have similar styles except in one specific case - CRED form parent post select fields. A parent post select field with more than 15 options will be displayed using a slightly different style that allows users to type and search for an option. This format tends to work better with lots of options, whereas a simple select field is easier to use with fewer options. I am attaching some screenshots showing the difference between these two fields. Note that this is on a default theme Twenty Seventeen. Custom themes may or may not affect the display of these input fields.
This is the technical support forum for Toolset - a suite of plugins for developing WordPress sites without writing PHP.
Everyone can read this forum, but only Toolset clients can post in it. Toolset support works 6 days per week, 19 hours per day.
