Learn how to enable collision prevention display settings to prevent multiple sign-up forms from appearing simultaneously or one after another for your shoppers. If you have multiple sign-up forms live on your website, each with its own rule-based display triggers, enable collision prevention to ensure that the forms won’t overlap and overwhelm your site visitors.

Enable collision prevention

You only need to enable collision-prevention 1 time in your form display settings, and it will apply across all pages on your website once set.

Note that enabling form collision settings will only block collisions between popup, flyout, full page, and banner sign-up forms. Embedded forms and custom-triggered forms will not be impacted by collision prevention display settings.

To enable collision prevention:

Navigate to the Sign-up forms tab.
Select the gear icon in the top right corner.

In Form settings, select Web if the Web and In-app options are shown. Check the box next to Don't show multiple forms at the same time.
Choose 1 of the following display settings:
Show only one form per session
Show next form after a time delay: Enter a positive whole number and choose seconds, minutes, or hours. The delay starts when a form closes.

Click Save.

Moving forward, your selected collision prevention display settings will prevent multiple sign-up forms from showing at the same time or in rapid succession. Keep in mind that:

Form teasers follow different rules Teasers shown before a form follow collision prevention settings. However, form teasers configured to appear after a form is closed can still appear when a visitor dismisses that form, even with Show only one form per session selected. The time delay between forms does not delay that form’s own teaser.
Frequency settings may be impacted by form display settings If you configure your display settings to Show only one form per session, each visitor will see only 1 eligible form automatically during their visit, even if that form’s Frequency setting allows it to reappear 0 days after closing.

Choose which form appears first

With collision prevention enabled, use Display priority to choose which form appears first when multiple forms are ready to display at the same time. Higher-priority forms appear first. If multiple forms share the same priority, their order is not guaranteed. You can also adjust when a form becomes eligible using its trigger settings in Targeting & behavior.

For a form without an A/B test, go to Sign-up forms, open the 3-dot menu next to the form, and select Edit.
Select Targeting & behavior > Display.
Under Display priority, choose Low, Medium (default), High, or Highest.
Select Publish or schedule, choose the Publish now option, then click Publish now to apply the change to your live form.

For an A/B test, priority is shared across variations and is set on the main form.

The form ID is the 6-character code in the form editor URL (e.g., A12345). It identifies the form. Use different priority levels when you need one eligible form to appear before another.
