VALIDATION STEPS IN DETAIL
STEP 1
Before you start prepare a list of options and save it as shown below, this will be required in Step4. (I have saved my list starting from Cell A300)
A very important point to remember is that, never save your data i.e. the list that contains all your options , in a row or column that may accidentally be deleted, always protect the cells if you want to save it in one of the top rows.
STEP 2
First select the empty cells that you require for valadation, as shown below.
Next click on Data from the toolbar and then click on Validation
STEP 3
In the Validation window, select List from the drop down.
On the Source bar click on the box circled in Red
STEP 4
Now go down to the data list that we had saved earlier in Step 1 i.e. in Cell A300.
Select the list and click the small box, circled in red
A completed Validation will look like this:
