use

bxslider api - onsliderresize callback

readmore api - aftertoggle callback

bxslider can non-responsive events indirectly resizes it's dimensions. can "wake" directly resizing .bx-viewport.

  function bxadjust(idx) {      $('.bx-viewport').height("0").height('100%');   }

use simple function callback both onsliderresize , aftertoggle. working snippet below.

snippet

$(document).ready(function() {    var bx = $('.bxslider').bxslider({      adaptiveheight: true,      pagercustom: '#bx-pager',      onsliderresize: bxadjust    });  });    function bxadjust(idx) {    $('.bx-viewport').height("0").height('100%');  }  $('.readmore').readmore({    aftertoggle: rmadjust  });    function rmadjust(tgr, ele, exp) {    bxadjust();    if (exp) {      tgr = 'close';    } else {      tgr = 'read more';    }  }
