To configure display options for a nodequeue, go to Site admin > Configure Chemistry Nodequeue views. You will see configuration options for each nodequeue on the site (in the following screenshot, there is just one nodequeue, entitled "Example")
For each nodequeue, you can specify
- The number of columns used for the display
- Whether or not you wish to use a horizontal or vertical view mode. Please note that for the horizontal view mode, it is recommended that you specify either 1 column (full width), or perhaps 2 columns, but not more.
