@HansH: You should follow the following steps for the columns to the ‘latest from the editorial’.
i. Go to the patterns folder of the theme file, there you will find ‘latest-posts.php’.
ii. Inside the file you will find wp:query “perPage” :3 (i.e. default), please make it 4 or 5 as your site requires.
iii. Then go to the browser login to your admin section, Go to Appearance => Site Editor
iv. Now you will need to click on the list view icon(three horizontal lines)
iv. Select the ‘latest from the editorial pattern’ where you will need to click Qurey Loop => Post Template
v. There on the right side you will find the columns field where you can set the columns to 4 or 5 as you want
(Please view the attached image for detailed information)
Threadwears Corporate is also the same Threadwears Pro theme. It’s just one of the variations of threadwears pro that one can use as per as their requirements.
Thanks
