Topic: Sticky Content Cross Component Referral

Joao pro asked 6 years ago


Hello, I'm trying to use the mdbSticky directive but its failing to point to an element that is being rendered on a diferent component (Which is a fixed top mdb-navbar). Is this even possible or does the "sticky-after" attribute as to be pointing to an element on the same component? Thanks in advance.   EDIT: Assuming I have to place the mdbSticky and an id on the nav element generated by the mdb-navbar component how can I accomplish that ?

Dear Joao, I debugged this problem on the code you provided and unfortunately it looks like there are some problems with this directive that we need to fix. Regards, Arek

Dear @Joao 

I have investigated your problem - I've tried to find where this bug has a place. But after some digging in the code I've discovered, that there's no bug. Sticky Directive works fine.

The problem was with your code.

In the main-section.component.html you're having such line:

sticky-after="#navbar"

But you should use there a .navbar selector. I'll describe that why you should use the .navbar selector later. So your sticky-after input should look like the below one:

sticky-after=".navbar"

Explanation: sticky-after input requires to pass a CSS selector, not an angular selector. So in this way you would add id="navbar" to the mdb-navbar element.

But this also will not work, because mdb-navbar element hasn't got a height. So you can't stick element to another element which has no height.

But element which has the .navbar class got height value - to this element you can stick another element.

Best Regards,

Damian

Hello Arek Here is some sample code. Sorry for the long post I still haven't figured out how to use the post code wrapper properly. I can send you the example code via email but this will be nicer for other users facing the same question. Again my question is how can I point to the navbar with my sticky element that is on the right side container of the main-section component. Thank you, Joao app-component.html:
<app-navbar></app-navbar>
<div class="container">
<divclass="row no-gutters">
