Here is how to add our chat box to Wix so it docks to the page like normal instead of stuck in an iFrame:
Go to your Wix website editor, On the left hand side click “Add” select “More” from the side navigation and then select the box that says “HTML code” This will place an blank box in the middle of your screen, Above this box click on “Enter Code” button and paste in the below code where it says “Add your code here (HTTPS only)”.
Add your code in this code area.
Click update and close that box. Now right click on the HTML box that is currently in the middle of your screen. Select "Show on all pages" and select the option “Pin to Screen” from the navigation menu. Click on the bottom right or bottom left corner of the graphic (Depending on where you would like it to sit) then drag the slide for “Horizontal offset) and “Vertical offset” to 0px, You can then close this box and publish your site and your live chat system should now be working.
Please Note: That you will have to resize the HTML box to fit in the chat window when it is opened we found that 400px wide and 520px high works fine.
