Please make sure you are launching ZPX file using Extension Manager CC (not Extension manager CS6) This addon should show under "Others" In Extension Manager CC.
Please check the detailed steps to install it.
1. Download the ZPX file by clicking "Download Before/after image slider" button in the link below:
2. Once Downloaded, Launch Extension Manager CC and Click install and select the ZPX file. IT will be installed in "Others" tab
3. Once the installation is over please check Download folder and you will find a file named as musethemesbeforeafterimageslider.mulib.
4. Double click the file to add it to Muse.
If this is not the case please make sure Extension manager CC is upto date. You can Check it from Creative cloud application.
That was the problem! Thank you for your help.
Hey....curious if anyone who has used this Before/After widget has tried to change the location of the slider bar when you first see it? Right now it's down the center. I would like it to be about 25% on the left side of the image. I have looked through all the html, js/scripts files and have had no luck.
I think the best point of contact for this will be the widget developer to confirm if it can be customized the way you wish.
