Eae galera blz. I am in need of a help with the following effect. I have a button that when clicking it opens a list. But I want this list to take the entire screen. Except that when there is the problem, when opening it simply goes to the limit of the parent element, I can’t define the size that makes it cover every page (body), it is simply limited to the parent element, would have something to do to solve it ? I’m wearing the bootstrap. Edit: can do without the Fixed display? to not have the scroll bar.

  • "I can’t define the size that makes it cover every page" if you are inside another div and want to do this, wouldn’t it be better to open as a lightbox and occupy the whole screen? jquery has it ready

I believe that this way that you are thinking will not be possible, but if you change a little the way of thinking should already get the desired result.

Instead of "open a list," you could

  • add an element to the DOM where necessary; or
  • Display a previously hidden item; or
  • Leave an "empty" element prepared to receive the content you want and display it;

All cases are similar in terms of encoding. Here is an example of how the last option could be made.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<body>
    <div id="div_de_exemplo"></div>
    <a id="div_de_exemplo_close" style="display: none">close</a>

    <div class="container">
        <div class="row">

            <div class="col-6">
                <a class="btn btn-block nav-link" data-role="list" id="open">
                    <span>Open</span>
                </a>

                <ul class="list-unstyled bg-primary text-white" style="display: none">
                    <div class="row">
                        <div class="col-9">

                            <ul class="list-unstyled" id="list">
                                <li>
                                    <h3>teste1</h3>
                                    dassadasd dassadasd dassadasd dassadasd
                                </li>

                                <li>

                                    <h3>teste1</h3>
                                    dassadasd dassadasd dassadasd dassadasd
                                </li>

                        </div>
                    </div>

                </ul>
