Browser Support & 508 

Netscape 4.7 cannot display certain visual nuances of the standard tree control. This tree has no borders and the title height differs from the standard tree (figure 1).

Figure 1: Example of the Standard Tree	Figure 2: Example of the Tree in Netscape Navigator 4.7

The tree view is always opened completely in Netscape 4.7. It is not possible to expand and collapse nodes locally. The application has to handle these operations (requires server round-trip).

 

Editability in Style Editor

In the Style Editor, it is possible to modify the following attributes of the tree view control:

Group	Style	IE5 and above	Netscape 4.7
Level Background Colors	Background Color of 1st Level Background Color of 2nd Level Background Color of 3rd Level Background Color of 4th Level	x x x x	x x x
