Feature supports -hash filtering

Hello, I have a `hash` in my Redis instance. The `hash` has only a few `keys`, but many `values` corresponding to those keys. I want to filter the `fields` within the `values`, but when I tried entering a filter string with the following structure in the `filter` box on the page, it didn't work: `New_Monitor_Data:key1:field`. Is there any way to support filtering by field?

Also, the default width of the filter input box on the page is 15, which is quite narrow. Could you make it wider and align it with the left side of the screen? Like this:

grateful!

No file or test is named. Start at the hash view and its filter input, reproduce filtering with `New_Monitor_Data:key1:field`, and verify that field filtering works. Also verify that the filter input is wider and aligned with the left side of the page.
