The first set of the layoutPanel values are panels included in the "chrome" of the
page. This displays the account information, the navigation, and any messages to
the user. The second set of modules make up the title and form elements. Notice that
TimeRangePicker and SubmitButton have no layoutPanel value, but will inherit
from ExtendedFieldSearch .
The results panels all begin with a HiddenSearch module. All of the children of each
of these modules inherit this layoutPanel value.
Panel placement
For your dashboard panels, you will almost always use a layoutPanel value of the
form panel_rowX_colY .
A simple visualization of the layout produced by our modules would look like:
In our simple XML version of this dashboard, the layout was tied directly to the
order of the XML, like this:
<row>
<chart></chart>
</row>
<row>
<chart></chart>
<chart></chart>
</row>
<row>
<event></event>
</row>
