Return Results of Selected Text in Table

[Borgas]

Hi Forum

I need some help develop a formula for "filter" multiple text in just one result

I have a table of products with multiple categories assigned in same cell

Example Structure

ID	Product	Category
1	Product 1	Cat1, Cat2, Cat3
2	Product 2	Cat2, Cat3, Cat4

<tbody>
</tbody>

I have a list of the categories, how can i do another table, just filter for one "Categorie"

ID	Product	Category
1	Product 1	Cat2
2	Product 2	Cat4

<tbody>
</tbody>
