# Manage capping for Popunders and Fullpage Interstitials
While creating or editing a Popunder, Desktop/Mobile Fullpage Interstitial zone, Publishers have an option to enable/disable **capping** for their ad zone. With this option, Publishers may decide to manage capping (display frequency) on their side.
**Supported Ad Formats:** Popunder, Mobile Popunder, Desktop Fullpage Interstitial, Mobile Fullpage Interstitial.
## Setting Up
{% stepper %}
{% step %}
### Enable/Disable capping through the snippet
Disable the capping on the Popunder snippet. The `capping_enabled` or `ad_capping_enabled` needs to be set to false in the ad snippet
```js
```
```js
```
{% hint style="warning" %}
**Note:** You need to complete Step 2 and Step 3 to ensure the ad is not triggered on every click.
{% endhint %}
{% endstep %}
{% step %}
### Setting up Event Listener
The event listener needs to be set up for creativeDisplayed event to be able to store/increment capping counter on publisher side
```js
```
{% endstep %}
{% step %}
### Managing the page DOM
Based on the value of the counter, which may be stored in any way, the snippet should be excluded from being added in the page DOM. Can be done through FrontEnd or BackEnd(examples for both are as below).
{% tabs %}
{% tab title="FE Example" %}
```html
Example page
Test
```
{% endtab %}
{% tab title="BE Example" %}
```php
Test
Test
```
{% endtab %}
{% endtabs %}
{% endstep %}
{% endstepper %}
