Building Drop-Down Menu
Meilix Generator has a dropdown menu which consists of links to code, issues and different FOSSASIA projects. The drop down menu appears after clicking on 3×3 dots present on the top right corner. The menu gets closed while clicking on the same dots. We want the menu to close close when we click somewhere else on the screen.
The problem statement is to close the menu bar while clicking anywhere on the white screen of the web app.
For that I have to add a listener to the rest of the body to add class “hidden”.
We first remove the old onclick listener from the body tag which open the pop-up to show up the option. We replace it with its class.
<div onclick="document.getElementsByClassName('custom-menu-cont').classList.toggle('hidden')" class="custom-menubutton"> <i class="glyphicon glyphicon-th" style="font-size:20px;"></i> </div>
<div class="custom-menubutton"> <i class="glyphicon glyphicon-th" style="font-size:20px;"></i> </div>
Then the dropdown menu doesn’t open while clicking on the dots also. So we added a script outside the body tag to
- Open the dropdown menu pop-up on clicking on the 3×3 dots.
- Close the pop-up while clicking on that dots or anywhere on the white screen of the webapp.
We are working in html so we have to add the type of the script. We add the function hideDiv to open and close the pop-up while clicking on dots.
We then add the eventListener to hide the pop-up while clicking anywhere on the screen.
