The Expand Record functionality lets you view all the information in a record on an almost full-size page, eliminating the need to scroll vertically through fields. It displays the field values and the record logs in a card-like format featuring the changes made to the record, the modifier's name, and the modification's date and time.
Right-click on the record header and select the Expand Record option from the context menu.
Hovering over a card will display the three dots menu icon.
Click on the Menu icon and choose Expand Record from the context menu.
At the bottom left corner of the expanded record, you can find the number of hidden fields of the record in an 'n' hidden field(s) format. Upon clicking on the hidden field option, you'll see the expanded version of the same.
