I have a web template (liquid layout) and need to modify it.
The changes are shown in a sample file that I produced.
Any changes must conform to the original template and documented in the html file and css.
In detail the changes to be made:
1. Extend the left column at the top of the screen and enter the items displayed in the file template_final
2. Create a filter for the grid containing the textbox displayed on at least two lines
3. Create a form with 4 columns by inserting controls such as textbox, select, checkbox
All changes must be made without changing the current styles, but adding new.
