Once you have logged into the H5P website find the Create New Content button (it is usually on the Content tab of your account).
Add the name of your content to the Title field and then choose Column from the Select content type dropdown menu by clicking on the appropriate Use button.
Choose the type of content you want to add by clicking on the Content drop down menu.
The fields will then vary depending upon which type of content you choose but create the module as usual and then choose whether you want to separate the different pieces of content with a horizontal line using the Separate content with a horizontal ruler drop down menu.
Click on the Add content button to add the next module to your column. Once you have added all of the different types of content add any tags to the Tags section and choose whether you want to display the buttons listed above with your column.
Personally I would leave all of the buttons checked as per the default settings as it gives both you and your users more flexibility. Then click on the Save button.
If you click on the Embed button at the bottom of the column once it has been generated, you can copy the HTML code and embed it into a web page as in the examplevbelow. In this case I have used a collage followed by a multiple choice module.
