This recipe shows how to create a more stylish dropdown with JCloze using a table. See a demo.
First, create a prototype your exercise. I am going to use images of hats and gloves for a vocabulary exercise and a table to position them. My prototype looks like this.
Open JCloze and Insert->HTML Table. Generate a table, 4 rows by 4 columns without table borders; set the width to 700px.
To center the table, add a style declaration like this:
<table border="0" cellpadding="5" cellspacing=5" width="700" style="margin-left:auto;margin-right:auto;text-align:center;">
Insert the images and the words from your prototype. Create the gaps. Save and output to a web page. Here's the result.
