Example: List all pages, sort by code.

  <div class="form-group">
	<label>Email Template</label>
	<MvASSIGN NAME = "l.ok" VALUE = "{ [ g.module_feature_tui_db ].PageList_Load_All(l.pages) }" />
	<MvASSIGN NAME = "l.ok" VALUE = "{ [ g.Module_Library_Utilities ].QuickSortArray(l.pages,':code',1) }" />
	<select name="_customerupload_notify_email_template" class="form-control col-3">
		<MvFOREACH ITERATOR = "l.page" INDEX = "l.pos" ARRAY = "l.pages">
				<MvIF EXPR = "{ l.page:id EQ g.customerupload_notify_email_template }">
					<option value="{ l.page:id }" selected><MvEVAL EXPR = "{ l.page:name $ ' (' $ l.page:code $ ')' }">
				<MvELSE>
					<option value="{ l.page:id }"><MvEVAL EXPR = "{ l.page:name $ ' (' $ l.page:code $ ')' }">
				</MvIF>
		</MvFOREACH>
	</select>
</div>

Create a unique sort field by rolling through the array initially and setting up a slugified sort field.

<MvASSIGN NAME = "l.ok" VALUE = "{ [ g.module_feature_tui_db ].PageList_Load_All(l.pages) }" />

<MvFOREACH ITERATOR = "l.page" INDEX = "l.pos" ARRAY = "l.pages">
	<mvt:assign name="l._temp_array" value="l.page" />
	<mvt:assign name="l._temp_array:sort" value="slugify(substring(l.page:name,1,2) $ ' ' $ l.page:id $ ' ' $ l.page:code)" />
	<mvt:assign name="l.ok" value="miva_array_insert(l.settings:new_array,l._temp_array,-1)" />
</MvFOREACH>

//OK, this is smt code, got confused, but the idea is the same.

  <div class="form-group">
	<label>Email Template</label>

	<MvASSIGN NAME = "l.ok" VALUE = "{ [ g.Module_Library_Utilities ].QuickSortArray(l.settings:new_array,':sort',1) }" />

	<select name="_customerupload_notify_email_template" class="form-control col-3">
		<MvFOREACH ITERATOR = "l.page" INDEX = "l.pos" ARRAY = "l.settings:new_array">
				<MvIF EXPR = "{ l.page:id EQ g.customerupload_notify_email_template }">
					<option value="{ l.page:id }" selected><MvEVAL EXPR = "{ l.page:name $ ' (' $ l.page:code $ ')' }">
				<MvELSE>
					<option value="{ l.page:id }"><MvEVAL EXPR = "{ l.page:name $ ' (' $ l.page:code $ ')' }">
				</MvIF>
		</MvFOREACH>
	</select>
</div>
