Is it possible to use the Select Dynamic Cascade? Or is there another way? 51 Postsostap 9 months ago3Topic 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? 741 PostsOctopoos - Lioneladministrator 9 months ago2Level 1 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. Regards. 51 Postsostap 9 months ago1Level 2Thanks, 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 #__regionsOptions Value: «id»2nd field (End):SELECT name_city AS text, id AS value FROM #__citiesOptions 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. 741 PostsOctopoos - Lioneladministrator 9 months ago0Level 3 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 Regards.
