Users can embed the JetFormBuilder form using a shortcode, so this plugin is compatible with almost any builder that supports shortcode output.

Collaboration With JetPlugins

JetFormBuilder focuses on form functionality by providing 18+ blocks, multi-column layouts, custom HTML addition, inline field editing, and more. Users can further improve the user experience and make their site fully-fledged by integrating this plugin with other tools:

  • use JetPlugins to style the form and enrich the form functionality:
    • JetStyleManager to style the form blocks in WordPress Block editor for free;
    • JetEngine to work with dynamic content;
    • JetAppointment and JetBooking to use the Appointment Date field block, set prices, build the “Appointment – Provider” system, and integrate the form with WooCommerce;
    • JetThemeCore to add forms to single and archive pages, WooCommerce templates, CPTs, and/or CCTs;
  • install the JetFormBuilder Pro add-ons for sales, marketing, or payment processing purposes and enrich the forms by:
    • outputting multi-level Select field groups;
    • applying dynamic auto-fill to the Select or Address field blocks;
    • allowing users to log in by the provided email/login & password;
    • adding color picker functionality to forms;
    • displaying the form autosave progress;
    • scheduling the form availability;
    • limiting form response number per user.

That’s all about the usage of the JetFormBuilder’s forms on a free WordPress sandbox site by InstaWP and combining JetFormBuilder’s functionality with other JetPlugins.

The Repeater Field from JetFormBuilder allows users to add as many repeated entries as needed using the predefined JetFormBuilder fields (i.e., to add information on required additional services, guests, team members, photos, files, etc.).

Adding the Repeater Field to the Form

Open the form, find the Repeater Field block, and drag-n-drop it into the form.

The Repeater Field Settings

The Repeater Field has the following groups of settings: General, Field, and Advanced.

The General settings are: 

  • Field Label field to type the field label shown on the form; upper and lower cases, spaces, commas, etc. are available;
  • Form Field Name field to type the field name for further use this name in calculations; this field should contain only lowercase Latin letters, numbers, ‘-’ or ‘_’ chars, and no spaces;
  • Field Description field to type a text to explain something to users;
  • Default Value field to type a default value or to select it from a source as Post, User, URL Query Variable, or Option Page.

The Field settings are:

  • Manage Repeater Items Count drop-down menu allows selecting the items count way: Manually or Dynamically (get count from form field)
    • If set, the default Manually option will enable users to add as many entries as they need; this option turns on the Add New Item Label bar to click the button for adding a new entry. 
    • If selected, the Dynamically (get count from form field) option turns on the Field Items Count drop-down menu to choose the form field to get the count.Calculate Repeater Row Value drop-down menu has two options: Default (returns rows count) and Custom (calculate a custom value for each row). The Custom option sets a math formula to calculate field value if selected.

Adding Calculated Fields

Users can add the Calculated fields into the Repeater field or outside the Repeater for calculations. Find the Calculated Field and drag-n-drop it where you need.


Use the JetFormBuilder macros (i.e., booking macros) for price settings such as seasonal prices, rates, and outlet prices. This macro takes all this into account and gives the correct costs.

Navigate to the Repeater field settings to calculate the formulation inside the Repeater field.

Select the Custom (calculate custom value for each row) option from the  Manage repeater items count drop-down menu. This option turns on the Calculation Formula for the Repeater Field on the top of the Repeater Field to add the formula for calculations. For example, the form below calculates the additional service costs for each guest using the Calculated Fields.

To use the data calculated by the Repeater field to the Calculated Field, add the Calculated Field and type the needed formulation. Add the Repeater Field name into the formula to use the repeater data.

Using Meta-Fields for Calculations

To calculate the total costs for the CPT, use its meta fields. The formulation with meta fields will look as follows:


(here, the booking_price is a CPT meta field).
