When writing a web program. Many places are applied to layers (DIV), DIV forms can be customized, flexible, but the main problem is that it is an element in the HTML page, and the location cannot exceed this page or Frame. For some system elements such as ActiveX controls or SELECT controls that cannot be placed. The advertisements that we often have seen from the web are often floating to the SELECT control, which is caused by the limitations of the DIV emotion.
In order to solve this problem, I have reviewed a lot of information. Finally, I saw an example on a foreign website. Its implementation is to use a web page instead of DIV, this idea is very good. The web page can break through the limitations of DIV. So there is this DHTML menu.
