Row, Col problem (new)

hi guys ~
i am always grateful for your help !!

I made 2 buttons in a row using ROW, COL. (button1, button2). ← like this
Row = R, Col = C

it worked, however the same code didn’t work in the multi page dash app.
button2). ← like this, not in a row…

this is my code below, please tell me that i didn’t know about this ~~

HI @Y.J,

what is R and W ? Are you using bootstrap?

I think we will need more information to help you.
