how do I make the additional details drop down always visible by default on time registration screen

​@blake.hamlin there is not a settings available for the end user to control the default visibility of the “Additional Details” group. 

However you can make it visible by default by using the ‘Page Designer’ editor with the following steps

1. Before you open the “Report Time” dialog, open the Page Designer editor from the Time Registration page (from the top right user menu)
2. When Page Designer is loaded switch the editor to show the “ReportTimeDialog”

3. 

   Now open the Content / Additional Details branch. Make sure You are in the right branch as there might be several nodes named “Additional Details”. Click twice on the “Collapsed” tickbox. 

4. 

   Save and publish the changes. Now when reloading the Report Time dialog the additional details group is not collapsed

Hope this helps. I’m not sure what version you are in so there might be some differences to my examples from 24R2.
