I recorded the video: https://drive.google.com/file/d/0BwwtdiiwgZwtycLWc5RFFaM2R0Rlk/view, after pressing the button there is a delay of about 2 seconds. I used the following add-in for views https://github.com/JKnorr91/ion-slide-box-tabs
Is this an Ionic v1 project?
Yes! ionic v1.
But in version 2 doesn’t this problem? If, no, how i can move slider to version 2?
I have no idea, but you didn’t choose the “Ionic v1” category so I fixed this for you.
