[Plugin: Custom Field Template] singleList

I have one question:

The textarea can be used as “singleList”.
(Adds the attribute of singleList attribute in order to output with <ul><li> if the value is single. ex) singleList = true)

This is my code to create the single list:

[fragen]
type = textarea
label = Zentrale Fragen
rows = 10
cols = 60
singleList = true

When I look in my database, the input is not saved with <ul><li>.
There are <p> and <br/>…

Can somebody help me with this problem?
