This video is about creating Passive or Web Tree Style Functionality, in Unreal 5.4 Blueprints.
We start by adding the IsMaxLevel function to the Web Tree Button Widget, and then the Highlight function in the Web Tree Line Widget. Next, we update the Web Tree Widget to fill the Buttons and Lines containers, which are then used when a Button is Leveled to Max to update the Buttons and Lines in the Web Tree UI.
