Example Explained
We have styled the dropup button with a background-color, padding, etc.
The .dropup class uses position:relative, which is needed when we want the dropup content to be placed on top of the dropup button [using position:absolute].
The .dropup-content class holds the actual dropup menu. It is hidden by default, and will be
displayed on hover [see below]. Note the min-width is set to 160px. Feel free to change this. Tip: If you want the width of the dropup content to be as wide as the dropup button, set the width to 100% [and overflow:auto to enable scroll on small screens].
Instead of using a border, we have used the box-shadow property to make the dropup menu look like a "card". We also use z-index to place the dropup in front of other elements.
The :hover selector is used to show the
dropup menu when the user moves the mouse over the dropup button.
