GWT Suggestbox with Smartgwt

问题:

I am facing a problem that I can't see the drop down list of the GWT Suggestbox. I am adding a GWT Suggestbox into SmartGWT's VLayout. Then I can see the textbox of the Suggestbox. But when I input some data, I can't see the suggestions provided. Is this because I am using the SmartGWT VLayout? Could anyone tell me how to solve it? Thanks.

Sorry, the above question is not clear enough. What I mean is I add a SuggestBox into a layout with small height. Then I can see the the SuggestBox's TextBox part and part of the suggestion and the rest of the suggestion seems hide under other layout. Below is my code:

VLayout mainLayout = new VLayout();
mainLayout.setHeight100();
mainLayout.setWidth100();

MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
oracle.add("a");
oracle.add("aa");
oracle.add("aaa");
oracle.add("aaaa");
oracle.add("aaaaa");
oracle.add("aaaaaa");
oracle.add("aaaaaaa");
SuggestBox box = new SuggestBox(oracle, new TextBox());
VLayout suggestBoxLayout = new VLayout(); 
suggestBoxLayout.setHeight("10%");
suggestBoxLayout.addMember(box);


VLayout body = new VLayout();
body.setBackgroundColor("#3B5998");
body.setHeight("90%");

mainLayout.addMember(body);
mainLayout.addMember(suggestBoxLayout);        

So when I enter a into the SuggestBox, I can only see a, aa, aaa and the rest suggestions are hide by the body.

This may be zIndex related, but there's no reason to use GWT's SuggestBox and run into problems like this. Use SmartGWT's ComboBoxItem. If you don't want a drop-down control to appear at the end of the text entry area, call setShowPickerIcon(false).

With the help from Alain, I add .gwt-SuggestBoxPopup {z-index: 1000000;} into my CSS. Then I solve the problem.

It would be easier with little bit of code. Before stopping to mix Smartgwt with Gwt I integrated some code which was using GWt suggestBox and it was working.... (Why don't you use the Smartgwt selectitem it does the job?) Regards
