<select> out of HTML-AREA in web-client

Hello,

Have implemented manually html code for HTML-AREA and I dynamically fill it’s drop-down

<table><tr><td><select style="width: 400px;" multiple="multiple">

Drop-down’s size (number of options) is unpredictable and trouble occurs when filled drow-down is larger than the HTML-AREA, so some options are not visible.

Is there a way to tweak the size (height) of
