Want to trigger a popup exactly when a user clicks a specific element? With PopupKit’s Custom Selector Click feature, you can turn any button, menu item, or text link into a trigger.

How to Show a Popup on Click (Custom Selector) #

Follow these four simple steps to set it up.

Step 1: Set the Trigger Event to Custom Selector #

First, you need to tell PopupKit that this specific popup should only appear when a user performs a click action.

• Open your PopupKit campaign editor.
• Navigate to the Display Options tab on the left sidebar.
• Locate the Open Event dropdown menu.
• Select Custom Selector Click from the list.

• In the Selector Class field, enter a unique class name (e.g., subscribe-popup or promo-click).
  • Note: Do not include a period (.) before the name here. Just use the plain text.

Step 2: Define Where the Popup Should Load #

Even though the popup triggers on a click, you must define which pages are allowed to load the popup scripts.

• Go to the Display Conditions tab.
• Click the + Add Condition button.

• Under the Include section, choose your target location:
  • Entire Site: To make the click trigger work on every page.
  • Singular: To target a specific Page or Post (e.g., Select “Page” then choose “Wpmet Tutorial”).
• Complete your design in the editor and ensure the Activate Campaign toggle is ON.
• Click Save.

Step 3: Link the Class to Your Website Element #

Now, you need to “connect” your website button to the popup by adding the CSS class you created in Step 1.

For Gutenberg (Block Editor): #

1. Edit the page where you want the trigger to appear.
2. Click on the Button (or image/text) you want users to click.
3. In the right-hand settings panel, expand the Advanced tab.

1. Locate the Additional CSS Class(es) field.
2. Type in the exact class name you used in Step 1 (e.g., subscribe-popup).
3. Update or publish your page.

For Elementor or Other Builders: #

• Select your widget > 
• Go to Advanced > CSS Classes > Enter your class name.

Step 4: Verify and Test Popup  on Click #

Once saved, it’s time to see the trigger in action.

• Visit the live URL of the page you just edited.
• Click the button or element where you added the CSS class.
• The popup should appear instantly.

Pro Tip: If the popup doesn’t appear, ensure that the spelling of the CSS class in your Page Editor matches the “Selector Class” in PopupKit exactly.

By mastering the PopupKit Custom Selector Click, you can create a seamless, high-intent user experience that triggers engagement exactly when your audience is ready. You’re now ready to turn any element on your site into a powerful conversion tool!
