Is it possible to use the Select Dynamic Cascade? Or is there another way? 51 Postsostap 11 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? 739 PostsOctopoos - Lioneladministrator 11 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 11 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. 739 PostsOctopoos - Lioneladministrator 11 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.
