Topic: Table header defined as sticky header overlays option list of <mdb-select-2>

markusruderman free asked 4 years ago

Expected behavior

In our application we have a similar situation as shown in Figure 1: At the top there is a filter area with some selects, underneath there is, among other things, a table whose header is defined as a 'sticky header'. The option list of the selects may not be overlaid by the sticky header of the table.

Actual behavior

When using a select, the option list of this select is partially hidden by the header of the table - please see Figure 2. What options are there to solve this problem? If the table header is defined as non-sticky, the two components will behave correctly. However, this variant is not practicable for us - we definitely need a 'sticky header' for the table.

Hi @markusruderman,

Could you provide styles below for your styles.scss file?

.sticky-top {
    z-index: 10

It should fix the display header of the table.

Best, Konrad.
