Button to access overlay menu on my map with OpenLayers 3

I am trying to add a menu button on top of my map that, when clicked, will display a window. I have created the map div and the overlayMenu button div, but unfortunately, the button is not showing up where I want it to. I would like the button to be located close to the zoom buttons and for the white area to disappear.

Below is the HTML code:

<div id="map" style="width:100%; height:100%; z-index: 0">
<div id="overlayMenu" style="z-index:9999"></div>

Answer №1

To adjust the positioning of the menu button on the map, utilize the CSS Position Property.

It may be necessary to assign a positive z-index to the menu. Keep in mind that the z-index Property only affects "positioned" elements - those with a position other than static.

#overlayMenu {
    position: absolute;
    z-index: 1;
    top: 10px;
    left: 50px;
}

Answer №2

It's possible to use absolute positioning, but proceed with caution. If the map is smaller and doesn't fill the window, the button may end up floating aimlessly in space.
