Topic: StickyContent Weird Behaviour

junior5417 pro asked 3 years ago


Hi,

I'm trying to implement https://mdbootstrap.com/docs/angular/advanced/sticky/ but when I'm scrolling, the sticky content is being blocked by the sticky nav bar on top. How do i edit it to have some margin/offset on top when scrolling?

Dear junior5417,

I have investigated this problem, and it seems that the stickyAfter resolves your problem.

I've got a separated NavbarComponent which contains the navbar with .fixed-top class, and in AppComponent I have used this NavbarComponent before the code of a sticky content layout.

In the stickyAfter input I have passed a .fixed-top class, which is a selector for navbar (from now, the sticky elements have offset of height from navbar element).

The only thing which I need to add is a style which sets an initial offset for the first sticky element(position: fixed; top: 56px).

Please take a look at the below code:

NavbarComponent:

<!--Navbar-->
<mdb-navbar SideClass="navbar navbar-expand-lg navbar-dark fixed-top indigo">

  <!-- Navbar brand -->
  <mdb-navbar-brand><a class="navbar-brand" href="#">Navbar</a></mdb-navbar-brand>

  <!-- Collapsible content -->
  <links>

    <!-- Links -->
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link waves-light" mdbWavesEffect>Home<span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link waves-light" mdbWavesEffect>Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link waves-light" mdbWavesEffect>Pricing</a>
      </li>

      <!-- Dropdown -->
      <li class="nav-item dropdown" dropdown>
        <a dropdownToggle mdbWavesEffect type="button" class="nav-link dropdown-toggle waves-light" mdbWavesEffect>
          Basic dropdown<span class="caret"></span></a>
        <div *dropdownMenu class="dropdown-menu dropdown dropdown-primary" role="menu">
          <a class="dropdown-item waves-light" mdbWavesEffect href="#">Action</a>
          <a class="dropdown-item waves-light" mdbWavesEffect href="#">Another action</a>
          <a class="dropdown-item waves-light" mdbWavesEffect href="#">Something else here</a>
          <div class="divider dropdown-divider"></div>
          <a class="dropdown-item waves-light" mdbWavesEffect href="#">Separated link</a>
        </div>
      </li>

    </ul>
    <!-- Links -->

    <!-- Search form -->
    <form class="form-inline waves-light" mdbWavesEffect>
      <div class="md-form my-0">
        <input class="form-control mr-sm-2" type="text" placeholder="Search">

noted, anyway to add margin-top: 56px only when the sticky is activated and while scrolling?


Damian Gemza staff answered 3 years ago


Dear Junior,

We have to investigate this problem, but it may take a while until we'll find some fix for this situation.

Until now, as a workaround, please add the margin-top style of value which mdb-navbar height is to every element which needs to be sticky.

So if your navbar is 56px height, add the margin-top: 56px to every element which is sticky.

Best Regards,

Damian

@Arkadiusz Idzikowski any solution for this issue?


junior5417 pro answered 3 years ago


I've included sticky-after="#yourHeaderElement", but is still not working. Does sticky-after="#yourHeaderElement" work if they are not within the same html/TS file?


Arkadiusz Idzikowski staff answered 3 years ago


Is it full html code of element with mdbSticky? Please try to use 'sticky-after' option as explained in documentation. For example:

<div mdbSticky sticky-after="#yourHeaderElement">

junior5417 pro answered 3 years ago


<div mdbSticky class="floatingDiv" #floatingDiv>
    Floating Div Content
</div>

<mdb-navbar #nav SideClass="navbar navbar-toggleable-md navbar-expand-lg double-nav fixed-top" [containerInside]="false">
    Navbar content

I'm suspecting the "StickyContent" for FloatingDiv is not working because my navbar has also enabled "Fixed-top". Please note that this two code snippet are from different TS. I have separated the header code and main body code into two different TS.

FYI, I also tested the Example Sticky Content code with "fixed-top" nav bar using the code snippet from https://mdbootstrap.com/docs/angular/advanced/sticky/, the result is the same as mentioned above.

Could you provide some html and ts code on which I will be able to reproduce this problem?
