Filter Table Inputs Forced to Text Inputs in v19 (Dropdowns, Multi-Select, etc. Not Working)

[osamaalnuimi]

Describe the bug

I’m encountering an issue with the filter table functionality in PrimeNG v19. It seems that all filter inputs are being forced into text inputs, even when they should support different input types like dropdowns, multi-select, checkboxes, etc. This behavior is also reflected in the official documentation examples.

Steps to reproduce the behavior

1. Visit the PrimeNG documentation for table filtering.
2. Check the examples for filter inputs (e.g., dropdowns, multi-select, etc.).
3. Observe that all filter inputs are rendered as text inputs, regardless of their intended type.

Expected behavior

• Filter inputs should respect their specified input types (e.g., dropdowns, multi-select, checkboxes, etc.).
• For example, a column with a dropdown filter should render a dropdown input, not a text input.

Actual Behavior:

• All filter inputs are rendered as text inputs, even when they should be dropdowns, multi-select, or other input types.
