The database has 2 tables:

1.#___regions

id name_region
1 Scort
2 Alabama
3 Texas
4 Rumba

2. #___cities

id Id_region class name_city
1 1 small Gor
2 2 large Fistashka
3 1 midd Hramka
4 2 small Beda
5 3 large Shopsa
6 1 midd Katol
7 1 midd Lima

.

I know how to use "Select Dynamic Cascade" to do this:

region: - Select an Option - ¬↓

city: - Select an Option - ↓

.

And me need to such:

region: - Select an Option - ↓

class : Select an Option - ↓

city: - Select an Option - ↓

.

That is to filter the list on the additional field "class" !

If not, what regular Seblod tools may be suitable for this?

Hi Ostap,

cascade can be done on multi level, so yes it's possible to do what you want.

You just need yo have relations between your differents tables.

Thanks, Leone for the quick answer! It's very important to me!

You said, "it's possible!" But I don't understand how?

In the first case, everything is clear. Write on in fields type "Select Dynamic Cascade»:

1st field (Start):

SELECT name_region AS text, id AS value FROM #__regions

Options Value: «id»

2nd field (End):

SELECT name_city AS text, id AS value FROM #__cities

Options Value: «id»

Parent: "id_region»

How in this situation between these fields to include the filter to the field "class" I can't think of.

Hi ostap,

  • The first Select will list Regions from the table #__regions
  • The second Select will list Class from the table #__cities, filtered by the Id_region of the previous Select
  • The third Select will display City Name from the table #__cities, filtered by the class of the previous Select
