Brizy

The popup builder of Brizy supports several trigger types. One of which is on-click. You can make use of this trigger type (on-click) to create the full-screen menu. The idea is, you create a popup and set the trigger type to on-click and then call the popup using a link. First off, go to Brizy - Popups on your WordPress dashboard. Click the Add New button to create a new popup. Give your popup a name and click the Publish button and click the Edit with Brizy button to edit the popup using Brizy. This will open the Brizy editor. Click the plus button on the canvas area to start creating the popup. You can either create the popup from scratch or from a premade template. To create the popup from scratch, you can simply click Create your own. Conversely, you can simply select a premade template you like to create the popup from a premade template. In this example, we will create the popup from scratch. Before setting the popup into a full-screen mode, you need to move the location of the close button which lies outside the popup by default. The reason is that the close button will be invisible on the full-screen mode if it lies outside. Click the X icon to show the settings bar and then click the third tab (from the left) on the appearing settings bar to set the close button location. From this settings bar, you can also set the close button color and icon size. Once done setting the location of the close button, the next step is set the popup background. To do so, hover your mouse over the popup and click the grey arrow icon. Click the Background tab on the appearing bar to use an image background. To use a solid color background, you can click the Colors tab.
