Web component in a grid-based layout

In a grid-bases layout, the item tag of the WEBCOMPONENT defines the default dimensions of the web component area:

LAYOUT
GRID
{
<GROUP g1                 >
[f1           ][f2        ]
[f3                       ]
 ...
<                         >
[f5                       ]
[                         ]
[                         ]
[                         ]
}
END

In the ATTRIBUTES section, use the SIZEPOLICY, SCROLLBARS, STRETCH and HEIGHT attributes, to define the sizing policy of a web component field:

WEBCOMPONENT f5 = FORMONLY.mymap,
   SIZEPOLICY = FIXED,
   STRETCH = BOTH;

By default, the WEBCOMPONENT widget gets the size of the form item. This is the behavior of SIZEPOLICY=FIXED, and is the only option.

Note: SIZEPOLICY=DYNAMIC or SIZEPOLICY=INITIAL are not supported with WEBCOMPONENT fields.
