how can i include caldera form in the post type?

I never used Caldera Form, and I don’t know how the plugin works. Since the form is not appear in the post type option, chances are the plugin has it own database table. And in this case it is not compatible with this plugin. Hence you can’t used this plugin to search the Caldera Forms content.

Thanks for the reply.

Can you recommend to me which Submission form plugin are suitable for me to compatible with Ultimate WP Query Search Filter or do you have suggestion of plugin that suitable for my submission and search form ( to retrieve data from database) ? I am just a beginner of using wordpress. i would like to create a submission form for y home tuition website that included: 1) New Tutor registration – Name , address ( State, Area ), Email address, Education level ( option : Degree, Master, Phd ),Student Level to teach ( Checkboc : Standard 1, 2,3,4,5,6,Form 1,2,3 )Teaching Subject ( Checkbox , option : English, Economics, Physics, Biology, Chemistry, Math, etc ), Available day ( Checkbox, option : Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday ), Available Time ( Checkbox, Option : If Monday: 8am-10am, 10am-12am,12pm-2pm,2pm-4pm,4pm-6pm,6pm-8pm)( If Tuesday: Checkbox, option:8am-10am, 10am-12am,12pm-2pm,2pm-4pm,4pm-6pm,6pm-8pm ), Tutor upload their own picture.

Then, I would like to create search form for user to search the tutor information from the database. Search form: (State ( Checkbox ), Area ( Get key in data ) , Student Level ( Get key in data ), Student Subject ( Get key in data ) ). The system search from database and display the result with the tutor picture.

I don’t think I can give you any recommendation. There are tons of plugins out there and there is no way I can try/examine which plugin is really fit your need.
I afraid you have to do your own study.

Then, can i know which search query and filter plugin is compatible with Ultimate WP Query Search and Filter? At least i can have targeted plugin to test.
