29. Make a table view “responsive” module: table trash While we cannot make a table view truly responsive, this does the next best thing. When the table view is displayed on a tablet or a phone, table trash hides the required number of columns so that the report will fit on the device. To expand the report the user can then click on the plus next to the line in which they are interested.

30. UHK Suggestions for Views • Name content types in singular • Names views in plural • Include node type in field name Example (1) • Easily find field in views list of fields. • If using multiple views: • “All displays” vs “this page” • Structure -> Views -> Settings • Show the SQL query • Make input required BEFORE views runs.

31. UHK Suggestions for Views • Page views with same path. • Bad – only one view will appear in the menu • Good – if the different views have different role permission, you can have multiple views under one menu item – and role appropriate view will appear. • With views aggregation – do not sort the data. Let the aggregation do it. • Don’t forget to put in No Results message in your view.
