Filters limit which forms are shown in the EGL form editor. You can define any number of filters, but only one filter can be active at a time. Filters affect only the presentation of the form group at design time; they do not affect the EGL code in any way. See Creating a filter.
You can switch between active filters with the list next to the Filters button at the top of the editor. To create, edit, or delete filters, click the Filters button.
