# IQL in Forms

> Use IQL in forms: advanced filters, behavior properties such as :hidden, :readOnly and :backgroundColor, and Run on click or Run on change actions like creating records or opening forms.

In forms, **IQL** can be written to filter records, to change behaviors of components, or as code that is ran on click or on change.

For code version control in the IQL editor, click on the ![ShowChangeInformationByLine](_images/form_designer/ShowChangeInformationByLine.png) icon to show change information by line, or click on the ![ShowHistory](_images/form_designer/ShowHistory.png) icon to show history.

Search for fields and variables used in IQL code with the [Find in form](form_designer/find_in_form.md) tool in Form designer.

> **Tip:**

> We have integrated Awen, our AI Assistant, directly into all Form rules editors. Instead of writing prompts from scratch, simply select any text and click the Awen icon next to the selection, to get an instant explanation.
