Although div cannot cover the select drop-down box, iframe can cover the select drop-down box, and div can cover the iframe , to achieve the desired effect through a series of coverage relationships between three elements. The implementation steps are as follows:
1. Create an iframe element of the same size as the div to cover the select drop-down box. And determine whether the iframe is effective by judging whether the current browser is IE6.
2. Let the div, select and iframe elements all use absolute positioning, so that the three of them are out of the document flow and can cover each other.
3. Determine the coverage relationship of the three elements by using the z-index attribute.
