Typeahead always shows only 5 suggestions maximum

Question

I have the below code using Typeahead.js for suggestions. I have no major issues on the code as it works fine.

The minor issue I face is that any given time, I see only 5 suggestions even though there are more than 5 suggestions from the remote URL.

var isearch = new Bloodhound({
    datumTokenizer: function(d) { 
         return Bloodhound.tokenizers.whitespace(d.value); 
    },
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    remote: "http://localhost/search/get-data/%QUERY"
});

isearch.initialize();  

$("#search_box .typeahead").typeahead(null,{ name: "isearch",
    displayKey: "value",
    source: isearch.ttAdapter(),
    templates: {
         suggestion: Handlebars.compile("{{value}}")
    }
});

What I expect is that there are more suggestions, there should be a scroll bar for users to see.

In Typeahead version 0.11.1:

Specify "limit" during the instantiation of the typeahead object to set the number of suggestions to display e.g.

// Instantiate the Typeahead UI
$('.typeahead').typeahead(null, {
 limit: 10, // This controls the number of suggestions displayed
 displayKey: 'value',
 source: movies
});

In Typeahead version 0.10.4.

The Bloodhound suggestion engine has a default value of five for the "limit" option (i.e. The max number of suggestions to return from Bloodhound#get)

You can increase the limit by specifying the desired value when you instantiate your Bloodhound object. For example, to specify a limit of 10:

var isearch = new Bloodhound({
 datumTokenizer: function(d) { 
     return Bloodhound.tokenizers.whitespace(d.value); 
 },
 queryTokenizer: Bloodhound.tokenizers.whitespace,
 remote: "http://localhost/search/get-data/%QUERY",
 limit: 10
});

An example of an instance of Typeahead where the limit is set to 10 can be found here:
