If I want to set a field as a css value.

i will make a new template, rather than duplicate a default one.

In this case I created a new template named 'profile'.
I copied the blogs' category template and default item templete, then modifiied theme to build a gallery.

I just make a test to add an item in some tag like <ul class="item">,whose position is called "color ".

But finally I want to make other category template named course.

All category items' style can selected from fields selector.
When I creat a new course item ,If i select 'mon' and class1 the tag will like <li class="mon class1">
"mon" will set the category item's positon in the monday row, 'class1' will set the item positon 'top:0px';.

hmmm ok.

And the code I added above doesn't do it?

Thanks !
I added it
but it still the same.T_T

Hmm.

Do you want each row in the list to have a color?
Then you have to put the code in the <li> tag and not the <ul> tag for starters.

But that doesn't solve the error though.

Can you please copy/paste some more code? Like from a couple of rows before the for loop and a couple of rows after.

EDIT:
Add this before your block as well:
<?php if (isset($this->item->positions)) : ?>

and this after:
<?php endif; ?>

Because if it's empty it might mess the foreach I guess.

It work!
I have find the problem.
<ul class="<?php if (isset($items[$i]->positions)) : ?><?php foreach ($items[$i]->positions as $field) : ?><?php echo $field->display; ?><?php endforeach; ?><?php endif; ?>">

Sorry! I lose <?php if (isset($items[$i]->positions)) : ?> :oops: :oops: :oops: :oops: :oops:
