Taglib documentation for tag mak:section#
Description#
A section that can be hidden, shown or reloaded using events. It enables partial page rendering via asynchronous post-back.
Sections that have a showOn attribute will not be displayed until the event associated to the attribute is fired.
Sections that have a reloadOn attribute will be reloaded via partial rendering (i.e. without reloading the whole page via a new HTTP request, but by reloading only the given section using an asynchronous request).
Experimental. Not yet used in production environments.

Examples#
Sections can be shown, reloaded or displayed using the mak.event(eventName, iterationExpression) javascript function.
<mak:section name="employees" reloadOn="reloadbuttonPressed" hideOn="hideButtonPressed" showOn="showButtonPressed">
<mak:list from="company.Employee e">
<mak:value expr="e.name"/> <mak:value expr="e.surname"/><br />
</mak:list>
</mak:section>
<br />
<button onClick="mak.event('showButtonPressed')">Show list of employees</button>
<button onClick="mak.event('reloadbuttonPressed')">Reload list of employees</button>
<button onClick="mak.event('hideButtonPressed')">Hide list of employees</button>
When a section is inside of a mak:list, it can be uniquely identified using the iterationExpr attribute, which should be a MQL expression that uniquely identifies one iteration of the list.
<mak:list from="company.Employee e">
<mak:section name="nameSurname" reloadOn="employeeRenamed" iterationExpr="e">
<mak:value expr="e.name"/> <mak:value expr="e.surname"/><br />
</mak:section>
<button onClick="mak.event('employeeRenamed', '<mak:value expr="e" />')">Refresh this employee</button>
</mak:list>
