If you want to display the business layout in home page as in our demo site then you need to follow the theme instruction. At first read the theme instruction clearly and still confuse then we are ready to help you based on our theme feature.
If you want to display the gallery (in two colum,three column or four column) then go to dashobard-> pages->new page
create a new page and assign a template from right side of the page there is template and select it from dropdown and click on update / publish
after doing this we have a custom post type galleries. first you create category and after that you can add the image by clicking on add new items.
to display the image you need to make the featured image from right bottom of the gallery page and publish it.
Thank you!
Thank you!
