It seems that i can't get to find workaround for this, maybe custom walker ? 

Im building a plugin and i'm listing all the inputs from database on one of my plugin page.

In the database i have list of categories id's which i retrieve in list. Categories id's are comma separated so it looks like

```
2, 32, 198, 23

```

As i understood the best way to retrieve those categories is with 

```
wp_list_categories

```

So if i take a field value from database and insert it in wp\_list\_categories i get this

```
wp_list_categories(array( 'include' => 2, 32, 198, 23 ));

```

Which is working code and with this i output specific categories which i want.

The problem is that this outputs a list of categories as ul and li elements with link to each category

And this is not what i want. I want to get output of categories but comma separated and i don't need to link to each category

So in the end i need to get output of this

```
Category 2 name, Category 32 name, Category 198 name, Category 23 name

```

What are the options to do this. I was searching and maybe custom Walker would work which replace ul and li elements with comma but i don't have a clue how to format a Walker class.
