Debut theme / I need help setting the slick slider vertical option.

[YongSik_Ou]

Hello

I applied a thumbnail slider to my homepage.

But this slider is horizontal.

As far as I know, the slider of the debut theme uses a click slider. As far as I know, there is an option to apply the slider in the vertical direction in the flick slider. this site: (https://kenwheeler.github.io/slick/)

But I need help with which area to put the 'vertical:true' code in 'theme.js' file.

I would like to get advice on how to apply the vertical slide option on the slide.

Please help me.
