Dynamic Logic

A dynamic behavior for forms can be achieved by utilizing the Dynamic Logic feature.


Dynamic Logic parameters are available for every field (Administration > Entity Manager > {Entity Type} > Fields > {field}.

The Dynamic Logic allows to define conditions making certain fields visible, required or read-only. Conditions will be checked automatically when data in the form is changed.

For Enum, Array, Multi-Enum, Checklist fields it's, possible to define different sets of options that will be available for the field depending on which condition is met. Note that the order of option list is taken into account.

For Varchar and Text fields, it's possible to define a regular expression to check whether a value matches a specific pattern.

Dynamic logic can control:

  • Visibility − if the field is visible or not;
  • Required − if the field is required or not;
  • Read-only − if the field read-only or not;
  • Options − conditions that determine which options are available (for Enum, Array, Multi-Enum, Checklist fields);
  • Invalidity − conditions making the field invalid.

Conditions are configured through user interface, no coding required.

Condition builder


  • When a condition for a field checks the value of the same field, it may cause side effects. E.g. making a field read-only when the same field is not empty.
  • When defining enum options that depends on the current value of the field, you need to include the current value to the option set.
  • In some cases it may be reasonable to disable the inline-edit functionallity for a specific field as it may interfere with the dynamic logic.
  • Dynamic Logic operates fields on the form, it has no effect on buttons and menu items in the UI.
  • Dynamic Logic is not applied on the list view.


In the Layout Manager, you can specify conditions making a specific panel visible. Edit the panel to configure the dynamic logic.

Available in the following layouts:

  • Detail
  • Side Panels
  • Bottom Panels

It's also possible to define conditions on which a specific color will be applied to the panel.


To determine whether a record is being created, check whether an ID is empty. It can be useful to hide some fields when a record not yet created or to show some panel with instructions described in a note.
