How to make tags horizontal

Wich "tags" are u talking about my friend? Can you please update this issue with some more information and maybe a screenshot?

You can do this in css or use the Taxonomy Formatter module (http://drupal.org/project/taxonomy_formatter).

For the css you can add something like this:

.field-type-taxonomy-term-reference .field-label, .field-type-taxonomy-term-reference .field-items, .field-type-taxonomy-term-reference .field-item {
display:inline;
float:left;
font-weight:normal;
padding-right:10px;
}
