If a table contains elements that can be manipulated, action buttons appear above the table:
A checkbox for bulk editing appears in the table header, and a checkbox appears next to each element in the table.
To manipulate elements in the table, check the box next to each element of interest.
To quickly select multiple elements, hold down the "Shift" key and point to the checkbox with the mouse. It will immediately change its state.
In the list of actions, select the desired action.
Click the "Apply" button next to the action selection.
The actions will be applied.
Add a new element
If there is an "Add" button in the action buttons,
Clicking it takes you to the section for adding an element.
Delete All
Sometimes, you'll see a "Delete All" button next to a table.
Clicking this button will delete all elements in the table. Not just those that are displayed, but all elements.
Editing Table Data
If there's a "Save" button next to a table, you can edit the table's data.
Enter the new data in the fields and click the "Save" button. The data will be saved successfully.
When saving, you don't need to select the checkboxes next to the elements.
