In this task, you are given an input list. A list contains several comma-separated items written within brackets. You need to collate all the alphabetical elements at the start of the list followed by all the numerical elements of the list. Maintain the order in which the alphabetical elements appear in the given input list, and do the same for the numerical elements.

Example input: ['238', 'h', '92', 'U', '2799']
Example output: h, U, 238, 92, 2799
Example explanation: Here, the alphabetical elements in order in the list are 'h' and 'U', and the numerical elements in order in the input list are '238', '92' and '2799'. Keeping all the alphabetical elements at the start of the list, and the numerical elements at the end of the list in the same order gives 'h, U, 238, 92, 2799'.
