-### How to use the table collections
+#### Tables on narrow screen devices
+
+When AyaNova doesn't have enough width to display a full table it switches to a vertical display instead to avoid the need to scroll sideways. See the [data table](ay-start-form-data-tables.md) help page for more information. For the purposes of this help page we'll show full width tables but the functionality is the same.

+### How to use the work order item grand child collections
 
 All items below the Work order Item level are collections that display as a single edit form when there is only one in the collection or as a table when there are multiple items in that collection.
 
-For example, if there is a single Unit there is no need to take up space showing a table of one Unit so it displays as a single edit form area showing the fields of the work order item Unit record. However, if there are two or more Units then a table displays showing each Work order Item Unit record in a row and clicking on a row opens the edit form area below the table so _that_ particular row can be edited.
+For example, if there is a single Unit there is no need to take up space showing a table of one Unit so it displays as a single edit form area showing the fields of the work order item Unit record. However, if there are two or more Units then a table appears with rows representing each Work order Item Unit record in a row.
 
 This pattern is used for all the collections below the header so that the simplest possible interface is shown at all times.
 
+#### Selecting records for editing
+
+When there are multiple grand child records such as work order item labor records, clicking on a row in the collections table will select that record and the edit form below the collections table will switch the record selected for editing.
+
+The context menu for each collection will often have options that act on a selected record so you won't actually see the option in the menu *until* a record is selected.  When there is only one record it is by default the selected record.
+
+#### Adding and deleting collection items
+
+Each collection has a context menu button to the right of it's title:
+
+![Work order labor context](img/svc-wo-labor-context.png)
+
+Clicking on this button will open the context menu with options for _that_ particular type of item.
+
+![Work order labor context menu](img/svc-wo-labor-context-menu.png)
+
+Here we see the Labor items context menu. There are three options common to all collections:
+
+- _New_ `+` option is used to add a new record. The record is added here locally to be filled out in the form below the collection table and later saved to the server.
+- _Mark for deletion_ is available because we have a record selected in the collection table by previously clicking on a row. The record will not be deleted until the entire work order is saved.
+- _Mark all for deletion_ is used to delete **all** records represented by their rows in the collection table. The records will not be deleted until the entire work order is saved.
+
+Each type of collection has it's own particular set of context menu options documented in their sections below.
+
 ### Header
