How to make pretty size charts

You will need to find a similar item that already has a photo included in the size chart. Make sure you use one that shows the same area of measurements (eg hips and waist, or waist and inseam)

You can do this by going to Plugins - Nop Quick Tabs - Manage tabs

Search for an item that has the photo needed to create your new chart - click edit 

You will need to copy the coding to duplicate the image/chart. Click on tools - source code

Copy the information from source code (to later paste)

Go to the product you want to create a size chart for and click add new tab

Click on tools and then source code

Paste the copied information into the new source code box 

Click ok

Enter the system name and display name. Then enter the measurements required for the item you are adding

If you need to add/remove a row or column:

Open the source code again, copy the coding - this is just a precautionary step incase when you save, it doesn't - then you could just reenter the code instead of redoing it all
