Trouble dealing with a dropbox in a certain website

[shahin]

When it comes to choose any item from a dropbox menu or input anything for search using dropbox then I get stuck. I've got something similar here. My intention is to put a certain text "F10" in the searchbar within dropbox to find it. I'm very close but can't accomplish it. My scraper can click on the dropbox menu and write the specific search in the search bar but can't settle it there, i meant can't unleash the search. I've uploaded a picture below to let you know what I meant. Moreover, if there is any better idea to deal with this, then I would be very grateful. Thanks in advance.

Sub Test()
    Dim IE As New InternetExplorer, html As HTMLDocument
    Dim post As Object, elem As Object

    With IE
        .Visible = True
        .navigate "http://ebible.org/study/"
        Do Until .readyState = READYSTATE_COMPLETE: Loop
        Set html = .document
    End With
    Application.Wait Now + TimeValue("00:00:05")
   
    Set post = html.getElementsByClassName("app-list text-list")(0)
    post.Focus
    post.Click
    Application.Wait Now + TimeValue("00:00:05")

    For Each elem In html.getElementsByClassName("text-chooser-filter-text i18n")
        If InStr(elem.placeholder, "Filter...") > 0 Then
            elem.Click
            elem.innerText = "F10": Exit For
        End If
    Next elem
End Sub
