Drupal 7 Taxonomy and Inline Terms

I just received some website feedback regarding my Drupal 7 Taxonomy Reinvented post. Since the question is an interesting one, I thought it would be better to write a post so more people can make use of the answer.

The question from pantherqin:

I have installed drupal 7 alpha 5 on my server. And inputed several tag words in taxonomy.

And at content type - article, I added in "tags" at "manage fields". However when I created an article with tags "tagA, tagB, tagC", those three words are displayed in a column.

How can I make those tags to display in a row?

I remember in the past, those tags are displayed in a row, and right-aligned as well.

The taxonomy terms presented on the pages for both Drupal 6 are enclosed in an <ul> (Unorded List) tag. Without any theming your list would look like this without theming:

1. tagA
2. tagB
3. tagC

The basic theming in Drupal 6 removes the preceding numbers and the result is that they are listed as a column.

In Drupal 7 <div> tags are used to enclose each term instead, making it more flexible to theme.

Default presentation will be like this, again without theming:

Drupal 7 Core does not come with more than basic theming for the taxonomy. I suspect you are using the bundled Garland Theme and it will display the terms in a column like above. Here on Nutshell I am using the Bartik theme and it contains CSS styles for listing the terms inline.

So, the easy answer is that it is down to your theme when it comes to displaying the terms.

Personally I am looking forward to when the Skinr module is ready for Drupal 7 as it will offer great flexibility to manage displaying of tags.
