 Notice how we now have a new `#APEX$DOM_ID#` attribute? As the region-only template component doesn't render any wrapping HTML elements, you can place the identifier inside your template to reference the region in JavaScript or CSS.

 If your attribute type is the default "Session State Value", you get a select list with all page items. If you change this to "text," you can actually type something in yourself and still reference page items with substitution strings, along with the quick pick list. Why is this not the default?

 In the template component near the end, there are new section slots. Let's create a new one and only allow buttons in there. We can set our new slot as the default position. (Click to zoom in on the images.)

 Let's get more crazy and add another slot that allows any content.

+/>
 
 Note that we could also filter specific regions and item types to be allowed in the slot. This may also be useful for composing your own template components, where, for example, the project status list view template component only allows the project status template component to be included.
 
 I also added the slot to the HTML template. In the page designer, I added an input, a "Content Row" theme component, and an instance of the same template component again (madness!) into the slot. And it works great!

 ## Selection support
 
 For theme components like the "Content Row", there is a new Row Selection option. The four options are: None, Focus Only, Single Selection and Multiple Selection.
 
-<BlogImg filename="apex-24-1-tc-row-selection.png" alt="" />

+  alt="In the page designer attributes of a content row region is a new group called 'Row selection'. In there is a select list with the label type."
+/>
 
 None does not add any click targets to the rows. Focus does this with a visible outline appearing when you click a row. I guess this is useful for adding your own click listeners.
 
 For Single Selection, you get a new attribute called "Current Selection Page Item". Whenever you click on a row, the value of the column defined as "Primary Key" gets set to the page item. This is super useful to just add a dynamic action on the page item change event and do something with the selected row or submit it to a process.
 
 The last option, Multiple Selection, adds checkboxes to the rows. Again, the values of the primary key column get set to the page item delimited by colons. Another attribute appears in the page designer called "Select All Page Item". You can again select a page item, but this has to be of the type "Checkbox". When this is clicked, every (visible, not hidden by pagination) row gets selected. You can place that item on top of the region or even add a nice slot for it.

+/>
 
 In the pagination section, the number of selected records is displayed. This is a nice touch. One issue is that if you miss the checkbox by a few pixels, you click on one row and thus deselect all others. In my opinion, in multiple selection mode, the checkbox should be the only clickable element in the row.
